Both widgets are using the same store.
Now i add some new model into the database, then reload the store to get the latest data from database.
The grids data gets refreshed. The Charts data gets outdated.

Is this a bug? Or i need to reload the chart somehow? (haven't found anything in the api)

And another question: is there an API for the ofcgxt classes?

And one more 'bug':
The
buChartProvider.getPieChart().setAnimate(false);
does not set the animation of the piechart disabled. Why? Did i missunderstood the meaning of this method?

Sorry, but in the link i can't find the source code you mean. Anyway i guess you tried to just add data into the store, right?
My approach was to reload the loader. This uses an RPC Proxy to load data from my servlet.
Could the error be resulting from this?

Sorry, but i don't know why i should open up a new thread for this ...
If you want, just delete this post.
But as this is 100% ofcgxt related only, i posted it just here...
